FAT (File Allocation Table) — file system, which was used in MS-DOS. Logical disk with this file system has such partitions:
<ul>
	<li>Download sector</li>
	<li>The table of distribution of the files - FAT(2 copies)</li>
	<li>Root directory</li>
	<li>Files</li>
</ul>
For storing of files all available disk space for them devices on clusters. The FAT consists of cells, which point to some cluster on hard disk. If cluster belongs to file, then his cell contains the number of the next cell which belongs to this file too. If a cell point to the end of a file the cell will contain a value "FFFF". Unused clusters mark as NULL. "Bad" clusters mark by special code.</body>
